Fight!

Popularity

Styled-components is a highly popular CSS-in-JS solution, known for its large community and widespread adoption. It has gained significant popularity in the React ecosystem and is widely used in production applications. On the other hand, @primer/css is a package developed by GitHub using the Primer CSS framework and is relatively less popular compared to styled-components.

CSS Framework Integration

Styled-components provides a way to write encapsulated CSS inside JavaScript components. It is framework agnostic and can be used with any JavaScript framework, including React. @primer/css, on the other hand, is specifically designed to work with the Primer CSS framework and provides pre-defined CSS utility classes and components to style React components in line with the Primer CSS design system.

Developer Experience

Styled-components offers a highly intuitive and expressive API, allowing developers to write CSS directly within their JavaScript components. It provides features like CSS interpolation, theming, and props-based styling. @primer/css also offers a good developer experience and provides utility classes and components to apply predefined styles to React components, making it easier to style components quickly and consistently.

Performance

Styled-components comes with a runtime overhead as it generates CSS classes at runtime. It does, however, provide optimizations like automatic vendor prefixing and dynamic CSS injection to mitigate the performance impact. @primer/css, on the other hand, provides pre-built CSS utility classes, which can result in more performant styles since the styles are pre-defined and do not require dynamic generation at runtime.

Flexibility

Styled-components offers a high degree of flexibility as it allows developers to use all the features of modern JavaScript while writing styled components. It supports CSS features like media queries, keyframes, and pseudo-classes within the component definition. @primer/css, being based on the Primer CSS framework, provides a set of predefined styles and utility classes which can be used to quickly style components in the Primer design system, offering a more structured and consistent styling approach.

Maintenance

Styled-components has a large and active community, with regular updates and fixes. It has a strong maintenance record and is well-documented. @primer/css is developed and maintained by GitHub, ensuring ongoing updates and compatibility as it is an integral part of the Primer CSS framework, which is also actively maintained by GitHub.
